To all whom it may concern:

In other words, at their inner ends the yokes 3 are normally supported upon f the pivoted dogs 2 which hold them at such height as to maintain the cams t out Ofelia" gagement with the rollers 3, the cams this position of'the parts being held against. rotary motion by their engagc 'n'cntwith fixed stops 4 on the framework. When, however, the do aremoved, the cam yokes are tripped an allowed to drop, withthe co result that the coins are disengaged from the fixed stops and come into contact with one or the other of the rollers 3", causing. the cam yokes to be reciprocated in the I usual manner. The rollers e are provided '96. with pulleys 3 (see Fig. 8') which pre -Q driven from any suitable source of powers The'free end of each yoke 3 engages the lower end of rod 5 so that each key depres sion will cause one of these rods to be raised. At the back and front of the rods 5, which are arranged side by side in single row,

otally mounted in the machine frame. The rods are provided with projections or teeth .10, 11, underlying the rocking plates 6, 7, so that when one of such rods 5 L,

raised, the corresponding plates 6 or 7 will simultaneously be turned about its pivotal spective vteeth axis. For this purpose the rods 5 are made each with only one tooth 11 at a, leyel peculiarto itself to engage the respective rockmg plate 7 at the same level, as shown in- Flg. 3, and the releasing rods 5 are further oach provided with as many teeth 10 as there are rocking plates 6, in which case or actuating the plates (see particularly the constructional form represented, the ke sare arran ed in six tiers, each key of tier, with t e corresponding keys of the ther tiers, forming what is herein to d a grou so that there are sixtee rou s in a I. The system of perforatio is evised so that one perforation is coxn mon to all the keys of a given tier and the second perforation of each pair is a 'propriated'toa particular group. As t e rocking plates 6 and 7' serve to control the perforating devices, as hereinafter explained,

it is necessary that the same rocking plate, .7 should be operated by the depression of all the keys of-gone and the same tierfand that the same rocking plate 6 should be operated by the depression of all the keys ,of one and the same group. Consequently all the rods 5 appertaining to the keys ofthe same tier, 4

have their-teeth 11 all at the same level to engage a given one of the plates 7 While the rods appertaining to the keys of the same (group have their teeth 10 also arrange at the same level to engage one of the plates 6. For purposes of uniformity and the exigencies of manufacture, however, Each of the rods5 is provided with a full complement of teeth 10, this being permitted by the recessing or interruptions of the plates 6 which engage the teeth on rods of only one particular group, as above described. Further, there are provided. sixteen rocking plates 6 each appropriate to a p vrticular group,'which may conveniently be arranged, as in the constructional form exemplifiednhd as seen in. Fig. 4 especially; in two series of eight, with the respective shafts extending over half the width of. the

keyboard and end to end. 'It will also be seen in Figs. 4- and 13 that the rocking plates 6 are of different lengtbs,each engag ing with a certain number of releasing rods 5. As there are siX keys for every rocking plate 6, corresponding to the six tiers of the keyboard, the extent of the engaging portion of each. of those rocking plates corre sponds with the space occupied by six adjacent rods 5.

With each of the rocking plates 6, 7 there is engaged a separate rod 12 or 13, by 79 means of a projecting pin 12 or 13 on said rod entering a holcin the rocking plate. An upper rocking plate situated above one operated by a given rod 12 or 13 is provided with suitable openings, through which that rod may pass Without affecting the said upper rocking plate.

The rods 12, 13 are arranged in two parallel banks those of each bank adjacent to each other and at about the same distance 0 apart as that which is to separate adjacent erforations of transverse rows in the strip. l lach of the rods 12, 13 engages the undersurface of a twoarmcd lever 14 which, in its turn, engages a horizontal, pusher 15 35 (Fig; 3). When a rod 12 or 13 is raised, a punch 16 .carried' at the foremost end of the corresponding pusher 15, is moved forward and perforutes the strip 17. As both a rod 12 and a rod 13 are always raised at the same time, two perforations are always correspondingly made in the strip. The retur movement of each pusher 15 is effected by a spring 18.

In the foregoing construction, therefore, each of the rocking plates 6 is connected at its outer end to all of the rods 5 of one particular group and'at its inner end to a single one of the rods 12 which operates the punches 16 of one set, it being noted that the longer plates 6 between their ends (see Fig. 13) are reduced or recessed to avoid engagement with the projecting teeth 10 of the rods of the intervening groups; while the rocking lates 7, which throu h the rods 13 operate t e punches of the ot er set, are connected to the corresponding rods 5 in- .the several groups or those appertaining to the finger keys of the same tier, it being noted that such rods are provided withprojecting teetlrll only at the level of the particular plate with which they are engaged.

As also described above, the overlying plates 6 and 7, at the places where the rods 12 and 13 are located, are cut away or provided with openings to provide clearance for such rods (Figs. 4 and 13') so that the rocking movementof a lower plate will be transmitted to its own particular rod without imparting movement to the other rods which are operated by theremaining plates.

According to the above arrangement, the

punches or pcrfomtors 16 are divided into two sets, those. of one set corresponding in number to that of the horizontal rows or tiers of keys and each connected to and operated by all of the keys of its respective tier, and those of the other set corresponding in number to that of the vertical nvs or groups of keys, and each connected to and operated by all of the'keys of its respective tier. Hence the depression of an one .of the finger keys will result in the s1- multaneous operation of a pair of punches of the twosets irrespective of the location of the key in the keyboard, thus reducing maite y e n mber of punches that is re- :fjuiredto be employed in the perforation of move thedatter forward; .;During its jourjney past the perforating devicet passes between two lates23,23wl'1ich also act, as guides, for t e punches. After leaving the plates 23 23' the stri travels up-' ward to a guide roller 24 and t ence to a receiving! spool or reel 25.

The

feeding forward of the strip is eflected by the rocking plate 32, which, for this pur-' pose, has 'operatively fast upon its shaft 32' i a lever 34 which is connected to a spring 30 pulling upwardly thereon (Fig; 8). To

the lever 34: is pivoted a bar 35 to whose upper extremity, is pivoted "aspring pressed pawl 36 which engages with the teeth of a ratchet wheel 31, Fa .1,the movement of the bar 35 being such t at, for each complete reciprocation, the sprocket wheels 21 will "be tu ned to theexiient of one tooth of the Hitch t wheel 3L v This ascent of the plate 32 moves the bar 35 downward and causes the pawl 36 to engage'the next following tooth of the ratchet wheel 31, so that when the plate 32 is next released, the lever 34 is returned to its. original position by the spring -0and causes wheel. 39 by 1 a' friction couplin e strip 17 the sprocket wheels 21 to he correspondingly turned.

The reel 25 is loosely mounted upon its spindle 40 and is connected with the ratchet comprising a spring-pressed flan e 39? sidably connected to the boss of t e ratchet wheel. and pressed again t the end of the reel (Fig. 15).

In such a case it 126 world be necessary to insert quads or spaces in the aces between adjacent words to subsequent y obtain proper justificatio As it is impossible to know, duringthe actual composition of a line, whether or not the ill-f4 arm 42 whiehisronnect'ed with'thebefore 110 sertion of such quads will be necessary, the perforations required for these uads can only be inserted after the composition of the line is finished. The operator may-further require to form, by manual means, other pen forations such forinstance, as when a word or a line is to be omitted; i. e., to. rectify or compensate for mistakes made duringcomposition. In such a case a special perforation is made both at the beginning and at the end .of the line to be cancelled, which will render inoperative the' composing machine until such time as a second perforation present invention,-a slide 45, Fi

efl'ectsa re-starti'ng of the said machine.

In order to permit of the manual insertion of additional perforations as above mentioned, there is provided according to the 1 and 3,

movable up and down guide rai s 46; these.

latter have toothed racks 46 with which engage toothed wheels 46 the common shaft 46 of which is journ'aled .in the slide-45 and can be manually rotated by means of milled heads 47, for raisingand lowermg the said slide. The slide carries one or more frames 48 (in the example illustrated'there are two) through which passes the strip 17 and in which punches 49' are carried. As two perforations must always be made at each oper- 'ation, the punches 49 are connectedto ether .inpairs each pair by a bridge 50, an each bridge-can be pushed rearward by a knob; or handle '51 to press the respective pair.

of punches through strip 17. In the eonstructional form represented eachof the two frames 48 is provided with two'pairs of punches 49, so that in all, four additional palrs of perforations can be produced inthe s trip'17. For stbpping and restarting the'composing machine one pair '3 used in each case, the other two pairs eing .employed for controlling the release of: quads or spaces of respectively different .set widths. This arrangement thereforeconstitutes in effect an auxiliary perforating apparatus which .may be used to supplement the main apparatus or to produce perforations not provided for in the main keyboard or any other desired perforations.

. As already stated, the quads or spaces must be inserted between adjacent words, i. e., at

' those places where the so-called spacebands 'are located. I In order to be able to indicate without much difficulty, where these places are, means'may be provided whereby the perforations appertaining to the spaces, are rendered readily distinguishable from the other perforations. In the present example this result is attained by an inking roller 52 (Fig. 9.) 'movably mounted in front of the strip 17 and operatively connected with the space key mechanism (as will-subsequently be described) in such manner that every time the said space key is depressed and a space perforation is made, the inking roller and represented will be pressed against the strip to make thereon a colored impression, for. instance a I perforation or perforations which will serve for the release of -the required additional quads or spaces; The adjustment of the slide 45 for the production of perforations. appropriate to the stopping and re-starting .of thecomposing machine, is effected in the same manner as that last described. 2 At the end of each line, a perforation is producedbydepressing' a -special key 1", which will afterward serve for controlling certain operations necessary on the comple tion of every line, for instance, in the case a, of composing machines, the-raisingof the assembler in order t9 send away the'cdmposed line-to. the castingmech'anismand, in the case of' typewriting ,machines, the movements of the paper carriage and platen.- During the time occupied by this operation, the escapement or e uivalent mechanism of the composing mac ine or the type actuating mechanism ofja typewriting machine, as the case may be, must not be operated, because, in the case of com osing ma.- chines, the assembler would not e in position to receive the released matrices, and'lin the case of a typewriting machine, the type would impinge on Wrong parts of the sheet.- For this'reason the perforated strip must any operation, to suchan extent as .wi allow suflicient timefor themssembler or paper car riage, as the case inay be, to be restored to normal or starting position; in the case of composing machincgfromsay 16. to 18 ad; vancements of the strip will usually sufiice for this purpose. To feed forward the strip for the eriod mentioned above, when the perforation forsendingth'e line away has been made, the mechanism next described particularly in Figs. 3, -5,

8 to 13, is employed.

By the depression of'the special key 1' at the end of the line, as is the case with the depression of the other keys during the setting up of the line, a rod 2 is raised and v the respective cam at and yoke 3 are operatcd, this yoke engaging the under-surface 12.. of a rod 55 (Figs. 3 and 13) to the upper end of which is pivoted one arm of a"two armed lever 56 to whose other arm is pivoted a pawl 57 adapted to engage aratchet wheel 58 (Figs. 3 and 8 to 13) fast upon a 13 former, andthe lever 62 willconsequentlyf 1, to; effect the release'of .the respective camf'w4 and acon'sequent further operation of theratchet. wheel 58, So long as the roller n61: v. has presented to I it; parts of '60, 'offlthe' larger diameter, so a 13) againstwhichbears a roller 61 carried in one end of a lever 62'which, at its oppovsite end, engages the-undensurfacc of'the respective -keyrod 2; The cam. 60 is formed with a -recess-60'. (Figs. 3, 3 and 12 in which the roller 61 rests when the device is inoperative, As soon as the rod 55, by the depre ion of the special key I is raised,

Throu hout this operation the strip 17 is moved orward step by step so thatwhen it is afterward used for controlling a machine, the actual composing, typing or analogous initial operating-devices of that machine will remain inoperative, for a corresponding period. For this purpose a further cam 116,

Figs. 10, 11, 12 and 13 is secured on the shaft 59 and this operates a lever 11? the free'end of which engages the umlcr surface of one of the rods 2. he cam 1115 has two recesses 118, 119, and in the resting position, the recess 118 is in engagement with the roller of the lever 11?. When the cam llli rotates, the lever 117 is rocked and so long as its roller ongageswith the part, of the cams periphery which has the larger. radius, the respective rod 2 will remain raised. This ma 2, in the manner previously described in connection with tne keyrods 2, effects the actuation of a rod 5-5 which is provided with only one tooth E26 and con-sc uently each time it is raised, it will raise t e rocking plate 27 and efi'L-ict the movernent forward of the strip in the manner hereinbcfore described.

ing awayof the composed line or controlling or efl'ecting another correspondingly periodic operation, is produced by a cam 63 during the rotation ofthe shaft 59 on which i i said camis secured. This M11163 has a pro- 7 truding nose which coii rates with a lever (is pivoted co-axially with the levers 62 and 117. When the shaft 59,'during its rotation, and, through the nose 65 of the cam 63 causes the lever 64 to turn about its pivot, 5

heath a shoulder of one of the rods .2, raises ,theflatter, and'through it, in the knownmanner, effects the release of the respective cam 4, so that the yoke 3 of that earn, will raise the respective rod -.5 which, in the mannerv previous y described, will produce a spe- 17. The norinal position of the nose 65iof-the cam 63 is such that the said nose does not become operative until after the shaft59 has made a art of a rotation, and consequently the er oration resulting from this pp'eration oes sulting from the actuation of the key last previously struck, so that a space intervenes between said 'perforations'and when, afterward, the strip is used to control a composin machine, or a typewriting orothenmachine the last matr x released, for the last type-har-actnated has time respectively to reach the assembler-or to, return to, its n'ormalposition before, in the composing machine, the line is sent away, and, in the type' writing machine, the paper carriage hasioc been adjusted for the start of'a new line. The angular position of the nose 65, on the shaft 59, coincides with that of the recess I 119 of ca'm 116.

'In order to enable the operator to ascertain on every possible occasion what space is left in the line and. whether the spaces introduced int-0 that line are sufiicient to insure its proper justification, the following means have been devised: v Each of the rods 5 is connected with an angle lever 66 (Figs. 3 and 5)" pivotally engaging a pusher 67 having at its foremost end a tongue 68. The thickness of these tongues for different rods 5, varies according to. the thickness of the matrices and spaces respectively appertaining thereto, YVhen a pusher 67 is moved by its lever 66, the respective tongue engages beneath a roller 69" 1 pivotally mounted between two arms 69 (Figs. 4, and 5) so that a rocking shaft 70 to which these ari'ns are secured, is turned to a smaller or greater extent according to the thicluiess of the particular tongue. at the time projected beneath the roller (59. On one end of the rocking shaft 70. there is secured an arm 71 on which rests a rod 72 JWl'lOSB upper end engages the under-surface 6) which is free to oscillate upon a pivot 74, The other arm of lever 73 carries a stud "75 upon which are pivoted one or more springactuat'ed e'scapement :pawls 76.
